Abstract: The disclosed systems for varifocal adjustments may include a frame, an optical lens pair supported by the frame, and a flexure assembly. The optical lens pair may include a first lens that is movably coupled to the frame and a second lens that is fixedly coupled to the frame. The flexure assembly may be configured to constrain movement of the first lens to a substantially linear pathway. The flexure assembly may include at least one substantially planar flexure element having a first movable end portion coupled to the first lens and a second fixed end portion coupled to the frame. Various other devices, systems, and methods are also disclosed.

Abstract: The disclosed system for varifocal adjustments may include a frame, an optical lens pair supported by the frame, and a brake mechanism coupled to the frame. The optical lens pair may include a first lens that is movably coupled to the frame and a second lens that is fixedly coupled to the frame. The brake mechanism may be configured to frictionally stop movement of the first lens and to maintain a position of the first lens. Various other devices, systems, and methods are also disclosed.
